A Rare Case of a Direct Incarcerated Inguinal Hernia Containing an Epiploic Appendage and a Literature Review

Abstract

Inguinal hernias are a widespread condition, responsible for a large number of acute abdomen cases. Typically, indirect, rather than direct, hernias are the ones leading to complications, as a consequence of their narrower hernial defect. Our case concerns a rather rare incidence of a direct incarcerated hernia in a 71-year-old man who presented with acute pain in the left inguinal area. Upon clinical examination, an irreducible inguinal mass was palpated. Therefore, the existence of a complicated hernia was suspected. The patient underwent an emergency repair, during which it was established that the hernia was direct and incarcerated and that its sac contained an ischemic epiploic appendage. The hernia was successfully repaired with mesh, the patient recovered uneventfully and was discharged five days later. Despite the rarity of complicated direct inguinal hernias, they should always be included in the differential diagnosis of irreducible groin masses, because they can increase severe complications.
